We built it;
we know it best.

The original constructor of corrosion and abrasion resistant linings and structures worldwide. Specializing in the design and protection against the harshest environments in the industry since 1884.

REINFORCED
CONCRETE TANKS

Reinforced concrete tank

STEBBINS has over a half century of experience with the design and construction of lined concrete vessels for liquid containment, and thousands have been constructed around the world with most still in service after several decades. We have constructed vessels more than 50’ (15m) diameter to contain nearly 150’ (46m) of liquid head. STEBBINS’ unique monolithic construction methods allow for a continuously rising structure during construction, which includes the process resistant lining, concrete structural core, and non-metallic exterior. Additionally, the high loading bearing strength capacity of the structure allows for the support of exterior loads and can support ancillary equipment without structural steel framework.

 

STEBBINS has developed various proprietary techniques for the installation of nozzles and inserts in a concrete vessel for proper liquid containment through a monolithic structure. These techniques allow for nozzles to be installed as the vessel is built and the height increases, eliminating the need to return later to install them, which may possibly result in cold joints and potential leak paths.

PRESSURE
VESSELS

Pressure vessels

Projects involving brick and membrane linings for pressurized, high temperature service conditions are areas of expertise where STEBBINS rates second to none. Our robust linings can withstand harsh conditions where other bond dependent coatings, cladding, or solid alloys cannot.

 

We have lined more vessels of this type than any other company in the world. Projects include, but are not limited to, Pulp Digesters in the pulp & paper industry, Process Vessels reactors for methyl chloride, isopropyl alcohol, ethylbenzene, vinyl chloride monomer and cumene manufacture in the Chemical Industry, and Pressure Leach Autoclaves, Flash Tanks and ancillary vessels for the Metal/Mineral Refining Industry.

 

Our approach is based upon the development of proprietary formulae which considers not only pressure and temperature, but also the irreversible growth of ceramic bodies quite apart from thermal expansion. These formulae have been substantiated by the results of field strain gauge measurements as a part of our on-going technical development program.

SPECIALIZED
CONSTRUCTION

Process containment tank

REINFORCED CONCRETE CERAMIC CONSTRUCTION

Typically, we require the client to supply only a doweled foundation, on which STEBBINS constructs the vessel utilizing reinforced concrete and various masonry units. Most of these tanks are designed to handle operating conditions with a pH range of approximately 3 to 11 and temperature limits of approximately 212ºF (100ºC) for liquid and much higher temperature limits for gas. For more severe applications with pH and temperature outside above ranges, modifications to the basic design of this construction technique allow its use.

 

CHEMICAL RESISTANT LINER PLATE OR BRICK LINING WITH OR WITHOUT MEMBRANE OVER SUBSTRATE

The substrate is commonly carbon steel; however, retrofit projects may be installed over failed titanium, alloys, rubber or coatings with minimal surface preparation. In certain applications, after engineering review, STEBBINS can install a lining in a failed metal vessel as a life extension project.

EQUIPMENT

STEBBINS is familiar with all types of chemical processes, environments, and mechanics involved with chemical containment and industrial resources. The following is only a brief list of service we provide, particularly focused around the pulp & paper industry.

Bleach

Towers

We offer excellent resistance to hot oxidizing conditions and upset conditions. A very large percentage of masonry and membrane lined Bleach Towers around the world have a STEBBINS' engineered lining. Additionally, STEBBINS has developed very resistant mortars that offer exceptional reliability, which translates to less shutdowns and repointing maintenance. Our proven technology continues to be retrofitted throughout the World to promote asset integrity of Bleaching Systems not originally lined by STEBBINS.

Washer Vats, Wire Pits & Clarifiers

STEBBINS’ masonry linings have been used extensively to protect concrete or steel vessels in the stock preparation, bleaching and paper machine areas. STEBBINS' SEMPLATE linings offer excellent resistance to most of the conditions throughout the Pulp & Paper process, with HEDTILE and SCI Brick used in more severe applications. Our specifications are very economical while offering excellent resistance to mechanical impacts, abrasion and chemical/temperature upset conditions.

HD 

Storage Tanks

In 1959 STEBBINS, along with two process equipment suppliers, developed the concept of a Neck-Down High-Density Storage Tank. Since our first tank, we have constructed hundreds of High Density Neck-Down Storage Tanks. We have efficient design and installation references for High Density Pulp storage of 150 tons up to 1100 tons.

Causticizers

& Liquor Tanks

Several decades ago, STEBBINS developed SEMAG linings for hot caustic conditions. This engineered lining system has a long history inside Causticizers, Liquor Tanks and other vessels operating at high pH, under hot conditions. The development of SEMAG was a direct result of STEBBINS' combination of engineered solutions and manufacturing capabilities to produce a material that would reduce maintenance requirements and overall capital costs.

SO2

& CO2 SCRUBBERS

STEBBINS' constructed vessels can support large loads, which provide a benefit when considering smaller boiler wet Flue-gas desulfurization (FGD) installations, gas-gas heater (GGH) support or CO2 projects with supported stack. The stack, GGH, or large loads can be supported directly on the wet FGD absorber tower. The same holds true for process tanks, such as Mixing Tanks to support dry silos, etc. to provide an optimized footprint and project cost savings.

TMP

Vessels

(Refining & Latency Chests) The increase in temperature brought on by the thermomechanical process (TMP) has led STEBBINS to develop design standards and methods of construction that will resist hotter temperatures. STEBBINS has constructed most of the TMP plants in North America using its proven construction techniques.

Mineral Leach
Tanks & Thickeners

STEBBINS’ reinforced construction has been used on many large Mineral Leach Tanks and Thickeners for ore leaching and treatment of the acidic liquid. The vessels normally contain sulphuric acid and abrasive ore at over 200°F (95°C) under atmospheric pressures.

Chlor-Alkali

Vessels & Tanks

We have successfully lined many vessels for elevated pH service. These vessels include Chlorine and Fluorine Emergency Scrubbers, Hypochlorite/Brine Settling and Storage Tanks, Chlorine Disposal Tanks, and Neutralizing Tanks.

Storage Tanks

& Blocks of Chests

STEBBINS' unique construction method has been used on round/rectangular tank construction since the 1940’s for all types of process vessels for various Pulp & Paper applications. STEBBINS has built most blocks of chests and storage tanks in Pulp & Paper mills throughout North America.

DIGESTERS

& ACCUMULATORS

The reliability of STEBBINS' pressure vessel brick lining design is well known throughout the industry. STEBBINS' unique experience with pressure vessels and the development of SEMCO brick has enabled hundreds of digesters and accumulators throughout the world to operate effectively without the need for frequent maintenance work.

AutoClaveS & Hydrometallurgy

STEBBINS’ pressure vessel experience with hydrometallurgical processes dates back to the early 1940’s. STEBBINS’ acid resistant lining installations have proven to be highly resistant to harsh mechanical, thermal, and physical environments for Autoclave applications.

GENERAL

Retrofits

STEBBINS' lining systems can be installed in an existing vessel to enhance its life/resist new process conditions or a new vessel as the initial corrosion resistant lining. Vessel life extensions have been completed in corroded alloy, failed organic coated, and degraded rubber lined vessels. It has also been used to enhance a metal vessel that was nearing the end of its life, by using a lightly reinforced SEMPLATE lining system, negating the need for a new steel shell and extended plant shutdown.
